ZD Self-Balancing High Temperature Multi-Stage Pump

Self-balancing multi-stage centrifugal pump:Using advanced hydraulic models, we independently develop high-efficiency and energy-saving products; since the self-balancing symmetrical multi-stage pump rotor has no wear and axial pulsation of the balance plate, the alignment of the impeller and guide vane is always in ideal condition, and there is no Like the ordinary multi-stage pump structure, the efficiency drops significantly as the balance plate wears and the rotor parts move forward; and there is no leakage of balance water, which reduces the volume loss, improves the overall operating efficiency of the pump, and reduces the shaft power. The efficiency is on average 2%-3% higher than that of ordinary multi-stage pumps.

  • The ZD-type self-balancing brand symmetrical horizontal multi-stage pump is to meet the needs of users and accelerate the development of high-pressure multi-stage pump technology. It adopts the advanced technology of similar foreign products combined with the company's many years of design experience and uses the hydraulic model of high-efficiency energy-saving products recommended by the country. , a high-efficiency, high-pressure multi-stage centrifugal pump product researched and developed in accordance with API610 standards; it is a technology leader in the industry. It has the advantages of a wide efficient area, wide performance range, good cavitation performance, few wearing parts, and convenient installation and maintenance. The reliability is greatly improved, the trouble-free running time is more than 3 times that of ordinary pumps, and user maintenance costs are greatly reduced, thus reducing the life cycle cost of the pump. The high-pressure self-balancing segmental centrifugal pump innovates the structural form of the traditional multi-stage centrifugal pump. It cancels the axial force balancing mechanism of the multi-stage centrifugal pump. It is a D and DG multi-stage centrifugal pump using a balance plate or balance drum structure. Pump to good replacement. Since there is no balancing device, that is, there is no disk friction loss of the balance plate and no balance return loss, the pump efficiency is 5-14% higher than that of the same type of multi-stage pump. At the same time, it completely solves the problem of the balance plate and balance plate seat caused by the failure of the balance device. Wear or rotor seizure and other faults can greatly extend the service life of the pump. Years of operation have proven that the performance of this product has reached the advanced level of similar international products.
